Question

Explain how hydrochloric acid is a good conductor of electricity.

Answer 1

• Hydrochloric acid $\left(\mathrm{HCl}\right)$ is a strong acid that dissociates completely into its ions (H+ and Cl-) in an aqueous solution.
• So, the solution contains freely moveable ions which conduct electricity and becomes a good conductor of electricity.
• Reaction:

$\mathrm{HCl}\stackrel{{\mathrm{H}}_2\mathrm{O}}{\to }{\mathrm{H}}^{+}+{\mathrm{Cl}}^{-}$
